摘　　要：采用自顶向下基于知识特征的提取方法 ,在飞机目标红外特性分析的基础上 ,用三维灰度图像投影分解成两个二维平面图像 ,分别提取它们的边缘特征、不变性角特征和区域特征 ,并对特征进行了融合 ,得到飞机目标的灰度图像特征。结果证明 ,该方法大大简化了特征提取系统的复杂性 。A top to bottom method of feature extraction base on knowledge is presented. By the analysis of target infrared features, first the three dimension gray plane image is projected into two two dimension images, then the edge, angle and area features can be extracted respectively? These features are syncretized to obtain the plane's features. The conclusion expresses that the complexity of feature extraction system is simplified obviously and the circuit is easy to implementation?
